Modern humans roamed the planet as early as 200,000 years ago, and yet it was only about 50,000 years ago that advanced tools and art became widespread. Researchers have long wondered why it took so long for humans to create these changes in society and now, they may have the answer. It turns out that lower testosterone could be to blame.

"The modern human behaviors of technological innovation, making art and rapid cultural exchange probably came at the same time that we developed a more cooperative temperament," said Robert Cieri, lead author of the new study, in a news release.
